Ron Artest Throws a Punch

While an object technically wasn't thrown, Indiana Pacers forward Ron Artest threw a punch at a fan during what was perhaps one of the most ridiculous instances in professional sports.

Towards the end of the game, Artest and players of the Detroit Pistons got into an altercation. After things were settled down, a fan tossed a beer at Artest. That pretty much set off what became to be known as "The Malice in the Palace."

Artest found his way up into the stands and started altercations with the fans. Once back on the court, he had another altercation with fans. There, he punched one fan in the face (pictured).

Artest has been on a long road to recovery from this event. Perhaps changing his name to Metta World Peace will finally take him into the right direction.

Cubs Fans Throw Beer Cups onto the Field

While they have been getting more and more used to it over the years, one thing Chicago Cubs fans just can't stand is a bad call.

Wrigley Field lacks a jumbotron, so fans have to go on by what they see. In this incident, fans did not agree with a call made. In response, the bleachers went into an uproar, and the fans painted the outfield with beer cups.

Hot Dog! Hot Dog! Who Wants a Hot Dog?!

Look, I know a round of golf takes a real long time, and unfortunately in these PGA tournaments, they don't have a cart girl. Still, I don't think Tiger Woods was that hungry that a fan had to chuck a hot dog at the former world No. 1.

Well, he did it, and he was immediately tackled and removed from the event. The hot dog didn't hit Tiger, but one should never throw something when a man is lining up his putt.

Duck! No Seriously, There Is a Duck!

What is it with hockey fans and deceased animals that represent their team? I just don't get the joy in carrying that around all night until game time.

Well, in this instance, an Anaheim Ducks fan decided to toss a dead duck onto the ice. The video is real obnoxious. If the description holds true, that fan has quite an arm to chuck that from all the way up there.

What is next? Are Calgary fans going to start throwing lighters onto the ice?

Pizza Delivery at Fenway

If you are going to interfere with the game, you better make the catch!

In this game between the Boston Red Sox and Los Angeles Angeles, a fan got in the way of a foul ball that seemed catchable. While the fans likely didn't care since they essentially saved an out for the Red Sox, they seemed disappointed that the fan failed to make the catch.

What better way to describe your disgust then by chucking a slice of pizza at the guy. He already received a beer shower from running into his buddy, so the pizza likely didn't change his postgame laundry plans.

When Fans Get Bored, They Find Ways to Entertain Themselves

The Arizona State Sun Devils made a mistake during one of their 2011 football games. During the blackout game against the Arizona Wildcats, students were given pitchfork flyers to hold up during the game.

Unfortunately, that idea didn't exactly pan out.

Instead, students found a way to entertain themselves by turning the flyers into paper airplanes.

Throughout the game, the flying objects were being launched from the upper deck all the way onto the field.

Rat Attack

During the 1995-96 season, Florida Panthers winger Scott Mellanby killed a rat that entered the locker room with a puck prior to the first game of the season. He had two goals in the game, but they regarded his performance to be a "rat-trick" since he had nailed the rat, too.

What came of that story was many rat-themed celebrations during the Panthers' season.

During the NHL playoffs that year, fans tossed rats all over the ice after the Panthers scored their first goal of night.

The spectacle is quite amazing, but that was it for the celebrations. The Avalanche didn't allow the Panthers to score again, eventually leading to a Stanley Cup victory for the Avs.

Rat Attack Part II

Unlike the plastic rats that were thrown onto the ice during the Colorado Avalanche/Florida Panthers hockey game, a real rat was thrown onto the court when the Philadelphia 76ers were visiting the Utah Jazz back in 2002.

Apparently, a fan tossed the rat from the second deck while Allen Iverson was lining up for a free throw.

Iverson shrieked in fear and ran to the locker room (not really, but it certainly would have been funny).

Penalty, on the Crowd

People often like to make penalty calls while they watch a football game, but unfortunately, our voices are never heard.

In this case, a Boston College fan felt there was pass interference on the play, so he went ahead and threw the flag onto the field.

The funny thing is, even the ESPN crew got caught up in the mess.

I think this fan has a great idea. There should be one fan given the flag before every game, and at anytime they can make one call. Something they should have definitely considered tossing into the new CBA.
